Got XL for both my mini schnauzer and Lhasa Apso. Gorgeous, soft and thin. May not last very long. Hand wash and no drier may help. Wish there was more choice of subdued colours for the boys.My 10 year old dog suffers from anxiety in storms. Got these shirts for that reason. They have helped her enormously. She is less anxious and takes less time to recover after a storm. The shirts are colorful, lightweight, and snug yet stretchy. They wash well too.Was nice quality for summer time but to long for my dog .If you have only one dog and your dog doesn't go around other dogs or out in the yard to play, then these are for you. They are cute and soft, wash up well, but they get holes easily.I’m always buying my fur child new clothing’s this top is lightweight and cute. I would buy in other colors if they had some. Size was correct and shirts did not rip while plying at the dog park.This tank is very lightweight and perfect for the hotter months. I really enjoyed the colors and tie dye patterns. The shirts for very well around my dogs neck and chest however, they are too long still. They’re measuring chart they listed is helpful however I might have miscalculated my dogs length. Overall, a good product.This is how it REALLY fitsI have yet to find one that doesnt creep towards the backLove the material. Lightweight and hoping it keeps some of the sun from burning herI returned the size that said would fit her and ordered a size down. Im thinking i could have even sized down by two sizesMy dog is 13 lbs and size medium fits a little tight.
